l DRAFT-RIGGING FOR RAILWAY-CARS.

To all whom it may concern:

Y Be it known that I, JOHN F. OCONNOR, a cltizen of the United States, residing at Chicago, in th'e county of Cook and State of Illinois, have invented a certain new and Fig.- 2 isa horizontal section taken on line 2 2 of Fig. 1; Fig. 3 is a crossl section taken on line 3 3 of Fig. v1; Fig. 4 is a vertical .longitudinal section showing the position of the parts when in full buff; Fig. 5 is a perspective view of the front follower; Fig. 6 is a perspective view of the rear follower. Referring to the drawings, the numerals 7-.-7 indicate draft membersor parts'of the car frame to which the draft rigging is aplied. l p A stationary key 8 is mounted betweenthe draft members, 4its ends being secured within perforations 9 in said draft members. In preferable construction, the opening 9 receives a collar 10 with which each ref inforcing arm 11 foreach draft member is provided, .each of said arms having an opening 12 within which the ends of the key 8- are secured by suitablelmeans, preferably the bolts 13-l3. The said arms 11 are each forwardly extended, and each has a collar 14 entering an opening 15 with which each draft member is provided, the said collar surrounding an opening 16 in the said arm sufficiently longitudinally extended to permit thefree forward and rearward movement' of the ends of the coupler key17 therein. The coupler key 17 engages thevdrawbarf 18 to the draft yoke 19, the same passing through a transverse slot 20 in the draw-bar and registering slots 21-21 in the adjacent limbs 22u-,22 of the draft yoke 19. The limbs 22 of the draft yoke 19 are also prof vided with transverse slots 23 through which Specification of Letters Patent.

of the arms 26 and so alined as to permit the passage of the limbs 22 of the yoke 19 therethrough. .The said follower is also provided with transverse registering slots 30-30, which slots are formed through the forward portion of the block-like member 25, as indi# cated at the numeral 32 in Fig. 5 of the drawings, and through the arms 26-26 of the said follower, the surrounding wall of said slots in the arms of the follower being reinforced in preferable construction by the Apreferablv integral outwardly extending shoulder '31. yThe key 8 passes through said slots in the front follower, the slots engaging at their rearwardI ends against the rear edge of the key 8 in normal position of the parts of the draft rigging, and being forwardly extended to permit the rearward movement of the front follower upon the lsaid key 8 on rearward movement of the draw-bar. I A

The rear follower 33 comprises a blocklike member 34 having forwardly extended arms 35-35', suitably spaced apart .to permit the passage of said arms between the arms of the front follower; the said rear follower being provided with transversely extending slots36-36 passing through the arms 35, the wall surrounding said slots being reinforced in preferable construction by the preferably integral shoulders 37-37.

The followers are each provided on tlelr Patented Aug. 31,- 1915.-

inner faces with upper and lower spring seats 38, each seat/ being provided with a boss 39 to assist in holding in position the compression resisting members` hereinafter flasnribed. The compression resisting memiei comprise preferably an .upper set of springs Ll0 and a lower set of springs 41.

Each set of springs preferably consists of an outer coil 42 and an inner coil 43 nested therein. 4The upper set of springs 40 isseated between the upper spring seats of the Vfront andi-rear followers, and the lower set of'springs is seated between-the lower spring seats of the. front and -rear followers. In preferable construction, -a bolt 44 passes through eaChset of springs, each of said -boltsv beinghsecuredat its: ends in the front and rear -follower s,.` respectively, and preferably passing throughA the alined bosses 39.

The key 8 passes through the'perforations' 36 in the', rear follower,.the,said perfora A,tions registering with the perforations in the front follower, and the arms of the front and rear lfollowers overlap ing, as is clearly shown in Figs. 1 and 2 o the drawings. 'Innormal position of the rear fol-I lower the front ends of the slots 36 engage Vagainst the frontv edge ofthe vkey 8, the

said slots 36 f being sufficiently rearwardly 'exten-ded' topermit the forward movement of the rear follower upon the key 8. The

limbs ofthe yoke which pass through thek longitudinal slots 27 in the front follower, pass 'along' the inner faces of the arms 26 of the. front followerand along theouter faces ofthe arms 3 5. of the rear follower, the rear connecting member 47 of the draf-t yoke engaging against the rear face 48 of the rear -ollowenin normal position of the partsof the draft rigging.
